A.1.1 消息结构
每条消息由标识位、消息头、消息体和校验码组成。
标识位 消息头 消息体 标识位
A.1.1.1 标识位
采用Ox7e表示若校验码、消息头以及消息体中出现0x7e则要进行转义处理转义规
则定义如下:
0x7e<——>0x7d后紧跟一个0x02
0x7d<——>0x7d后紧跟一个0x01。
转义处理过程如下:
发送消息时:消息封装——>转义;
接收消息时:转义还原——>解析消息。
示例:
发送一包内容为0x30 0x7e 0x08 0x7d 0x55的数据包则经过封装如下:0x7e 0x30 7d 0x02
0x08 0x7d 0x01 0x55 0x7e。
A.1.1.2 消息头
消息头内容
一对请求和应答会使用相同的消息流水号。有分包时分包消息通知的流水号与请求一致。
起始字 字段 数据类型 描述及要求
消息类型
消息流水号 BYTE 对应不同业务,具体见消息体。
消息体长度 WORD 0-65535。用于并发是匹配应答
是否有分包 WORD 0-65535
分包总数 BYTE 0=无分包1=有分包
分包序号 WORD 无分包时无此字段
WORD 无分包时无此字段。序号从 01 开始。
A.1.1.3 分包
当消息体长度超过 900 字节时,需启用分包对消息体进行拆分。
同一个请求的多个分包需要使用相同的消息流水号,并按照顺序从 01 开始依次提供序
号。
当接收到全部分包后,服务器会发送消息类型 0xF0 通知接收完全。
当某个消息流水号的分包未接收完全,且 5 秒内没有接收到新的分包,则会发送消息类
型消息类型 0xF0 通知需补发的分包序号。
当某个消息流水号的分包最后一次接收分包的时间点超过当前时间 10 分钟,该流水号
的分包内容将会被舍弃。该流水号将会可以重新用于新分包消息。
A.1.2 消息体
由head参数体、data参数体和files参数体组成。
head 参数体 data 参数体 files 参数体
A.1.2.1 head参数体
